SPECIFICATION forming part of Letters I'atent No. 707,846, dated. August26, 1902. Application filed February 18, 1902. Serial No. 94.604. (Nomodel.)

To roZZ whom it may concern.-

Be itknown that LEDWARD M. HEYLMAN, a citizen of the United States,residing at J anesville, in the county of Rock and State of \Vis- 5consin, have inventedcertain new and useful Improvements inSeeding-Machines; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to seeding-machines of the class known assulky-listers, having seed-dropping mechanism mounted upon the plow-beamof a sulky-plow and operated by r the carrying-wheels of such machine.

The object of my invention is to provide such machines with meanswhereby the seeddropping mechanism may operate while the plow is in theground and automatically cease to operate when the plow is removed fromthe ground.

To this end my invention consists in combining with such seed-droppingmechanism a rotary shaft provided with a pinion oper- 2 5 ated by aconnection with one of the carrying-wheels and adapted to rotate saidshaft when the plow is in the ground and to rotate freely on said shaftwhen the plow is raised from the ground, so that said shaft and seed- 0dropping mechanism will remain idle at such time.

In the drawings, Figure l is a plan view of a sulky-lister embodying myinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a 3 5 planview, partly in section, of means for operating a rotary shaft connectedwith seeddropping mechanism. Fig. 4. is a sectional side elevation ofthe parts shown in Fig Fig. 5 is a plan view of a pivoted pinion-casing.Fig. 6 is an inner side elevation of such casing. Fig. 7is a rear viewof the same. Fig. Sis a front elevation of a bearing-bracket having aflange-cam. Fig. 9 is a side elevation of said bracket.

As illustrated in the drawings, the main frame of the machine consistsof a transverse arch A, mounted upon a crankaxle D and provided with astub-tongue B,secured thereto, having braces O secured at their forwardends to said tongue and at their rear ends to the arch A of the mainframe in any suitable manner. A lever F is connected with saidcrank-axle and provided with a latch f, adapted to engage a segmentalrack G, secured to the main frame, by means of which the crank of saidaxle maybe raised and lowered or moved forward and backward and lockedsecurely in the desired position. A plow-beam H, supporting a plow I, ismounted upon the crank of said axle by means of a bearing h and israised and lowered or moved forward and backward by a correspondingmovement of the crank of said axle. A seed-receptacle J is also securedto the said plow-beam and provided with a tube j, having its lower endarranged behind a subsoiler K and in front of coverers L, which are alsoattached to or connected with said plow-beam. The seeddropping'mechanismconnected with the seedreceptacle may be of any well-known constructionand is operated by means of a rotary shaft M, which engages a sleeve 0,having a gimbal-joint N or other loose-jointed connection with theseed-dropping mechanism. The main portion of the shaft M is rectangularand has a sliding connection with the rectangular sleeve 0. A pinion Pis loosely mounted on the round end of the rotary shaft M and isprovided with an extended hub 19, having its end indented to engage thecorresponding indented end of a clutch Q, which has a sliding connectionwith the rectangular portion of the shaft M. A collar R is rigidlysecured to the shaft M, by means of which this end of said shaft isprevented from sliding in the housing S, in which the round end of theshaft M is journaled. The hub 10 of the pinion Pisjournaled in thehousing S and provided with a shoulder 12, I which bears against suchhousing, which, together with the collar R, prevents an outward slidingmovement of the rotary shaft M. The pinion-housing S is constructed intwo parts, secured together by means of bolts, and such parts areprovided with semisockets forming 5 bearings for the pins t, extendingfrom the gear-casing T, thereby permitting a limited lateral swivelingmovement of the pinionhousing on the gear-casing. The gear-casing T isprovided with a sleeve 25, which is mount- 10o ed upon the crank-axle D,and the outer surface of said sleeve is preferably machinefinished, soas to form a suitable bearing for the hub of the driving-gear U, whichis-journaled on said sleeve. A lou'g'bearingis'thereby provided for thegear-casing T on the axle, and a closely-fitting bearing is alsoprovided for the driving-gear U of the sleeve of said casing, whichenables said gear to rotate evenly and smoothly on the sleeve of thegearcasing with a minimum amount of friction. By pivoting thepinion-housing S to the gearcasing T the driving-gear U and the pinion Pare held continuously in mesh and the rotating shaft M and pinion P,journaled in said housing, are enabled to swivel to the proper alinementas the plow is being raised or lowered.

The pinion-housing S is provided with an extension or shelf .9, uponwhich is mounted a bell-crank lever V and secured thereto by means of abolt and nut. One end 1; of said lever is bifurcated, so as to straddleand bear evenly against the clutch Q and move said clutch longitudinallyon said shaft against the tension of the spring Y, which is secured inplace on said shaft by means of the washer X and pin 00. The oppositearm of said lever is arranged in close proximity to an inclined plate orcam-flange w, extending outward from a bracket W, which bracket issecured to the main frame of the machine, preferably to the arch A ofthe main frame,and provided with a hub w, in which is formed a bearingfor one end of the crank-axle D.

' When in use, the driving-gear U is operated by means of a clutch onthe hub of one of the carrying-wheels interlocking with a clutch on saidgear and meshes with and operates the pinion P, which pinion is mount edfreely on the round end of the rotary shaft M and engages the clutch Qon said rotary shaft, causing said clutch to rotate and givecorresponding rotary motion to said shaft by means of its rectangularengaging connection with said shaft, and thereby operate theseeddropping mechanism connected with the seedreceptacle J. When theplow-beam is raised by means of the lever F, one end of the bellcranklever V comes in contact with the inclined face of the cam-flange w,thereby forcing the bifurcated end of said lever V against the annularshoulder q of the clutch Q, so as to force said clutch out of engagementwith the end of the pinion P and enable said pinion to rotate freely onthe round end of said shaft without imparting motion to said shaft orseed-dropping mechanism. however, the plow is lowered, thle clutch Q isforced into engagement with the end of the hubp of the pinion P bymipans of the spring Y, and the motion imparted to the pinion P by meansof the driving-gear U is transmitted to the shaft M by means of suchclutch and the rectangular connection between the clutch and therotating bar.

I do not desire to be limited to the specific construction of theseveral parts showh here- When,

of an arched axle, a gear-casing journaled on said axle and providedwith a sleeve, and a driving-gear journaled on said sleeve and operatedby one of said carrying-wheels, substantially as shown and described.
